One of the most interesting seminars I prepared this semester explored the muon anomalous magnetic moment (g-2) and its interpretation within the 331LHN model, following the research article:

arxiv.org/abs/2604.12755

Though the muon (g-2) anomaly weakened after theoretical QCD corrections in 2025, the ideas it motivated are still considered viable candidates for possible new physics. In this paper, the authors proposed a singlet scalar leptoquark in an attempt to explain the observed muon's anomalous magnetic moment, considering both the 2021 (when the anomaly was reported) and 2025 updated scenarios. It is also interesting to understand how theoretical ideas evolve in response to experimental results, especially in particle physics.

Leptoquarks have been new physics (NP) candidates since 1976, first appearing in the Pati-Salam model, and they have gained renewed research attention whenever anomalies have been observed, including RK, muon g-2, and others. Leptoquarks are hypothetical particles that mediate direct interactions between the quark and lepton sectors. Having such particles in nature would induce some interesting consequences in flavour physics, most prominently lepton flavour violation (LFV), which we already know is possible because neutrinos are massive. However, the allowed parameter space for this proposed new particle is constrained by precision measurements in flavour physics, as experimentally, LFV is extremely suppressed.

Working with the same motivation, the authors explored singlet scalar leptoquarks within the 331LHN model, constrained their parameter space, thereby governing how large the couplings and the mass of the leptoquark could be. The paper concluded by exploring the possibility of producing such an exotic particle at colliders.

Preparing this seminar as part of my course "Model Building: Physics beyond the SM" at TU Dortmund University; helped my understanding of model building and imposing consistency between new theories and established experimental results, which is a valuable skill for me as a student seeking to understand the intriguing structures in flavour physics.

Learning about accelerators, detectors, and beam physics in lectures is one thing. Seeing these technologies operating in world-leading research facilities is another. After our visit to CERN earlier this year, our recent study visit to DESY and the European XFEL offered a complementary perspective, highlighting how accelerator science enables interdisciplinary research spanning fields such as structural biology, drug discovery, materials science, chemistry, and clean energy.

During the visit, we explored the European XFEL, the PETRA III synchrotron, detector development laboratories, and several accelerator and test beam facilities at DESY. Each experiment offered a different perspective on modern research infrastructure and the many ways accelerator technologies contribute to scientific discovery.

Now it’s time to focus on exam preparation. Looking forward to sharing more experiences soon!

I was doing Signal extraction from raw Real LHCb data. Before starting the procedure, I could even cant see the signal popping out as it was hidden in the huge background- most prominent background is combinatorial background. Tried multiple times, sometimes the cut is too tight and end up with ill-looking plot. Other times, correlation matrix wasnt applied cleanly and so on. Mistakes helps you see the physics more than perfect solutions could. So its always nice to start from a draft and implement it. See how it works and then if it didnt work as intended then ask why. And start fixing it. Sometimes its not easy to figure out by yourself and you need help. However, learning is in this process while final milestone is finally getting the intended result. But either way, you always end up realising so many things that you thought werent important or didnt realise that they hold some crazy sensitivities.


Do you have something or story to share? Would love to hear from you all.

Have a good time! 💐

Experiments are far messier than we can imagine through clean theory, which is exactly what makes them interesting.

Take electrons, for example. At high energies, synchrotron radiation makes them inefficient as beams. Even as final-state particles, they’re not straightforward; bremsstrahlung leads to energy losses that complicate reconstruction and precision measurements. The R_K anomaly is a good reminder of how subtle these effects can be.

Then you compare that to muons; essentially heavier electrons, but experimentally much cleaner.

The scale and precision of particle physics measurements keep surprising me, and I’m still taking in how vast the field is.

Do you have such a moment when you already knew something but when you do the experiment you realised how strange or important that thing is? If yes, let me know in comments section.

Have a great time everyone!✨✨

Hello my Youtube family. As 2025 comes to a close, I want to share a reflection from my first visit to CERN earlier this month, in particular the ALICE experiment.

I visited CERN on 15-16 December 2025. I expected to be impressed. What I didn’t expect was how different it felt to see it with naked eye; and the little pauses it took to register that this was the same place I had only known through lectures, discussions, and images. Having studied these experiments and their underlying physics for years, standing there, surrounded by the scale and complexity of it all, I kept thinking the same thing: this place actually exists!

Standing next to the ALICE detector and realizing that conditions from just moments after the Big Bang are recreated there, in an extremely controlled, human-built environment, was genuinely astonishing. This is where quark-gluon plasma is explored. This is where abstract concepts from theory take physical form. Humans built this, and we are still pushing it further. It’s a true wonder.

A few days later, something quietly completed the experience for me. My sister told me she had been teaching her students about the Higgs boson and mentioned that it was discovered at CERN. In that moment, I remembered myself years ago, sitting in a classroom, first hearing about CERN and imagining what it must be like. Realizing that I had now spent a day there, witnessing it firsthand, felt like a full circle.

I am deeply grateful for the journey that made this possible. Alhamdulillah.

With this reflection, I want to thank the IMAPP program and wish You all a thoughtful and meaningful New Year. Happy New Year everyone 🥳🥳🥳

Now everyone has their own timezones so you know. Accept my wishes and all the best for your future 💕💕💐💐

Hello Everyone! Just wanted to share that I will be uploading your requested videos very soon. I have just continued my own studies so was quite busy tackling everything. I hope you all are having fun with Physics and let me know your favourite thing from this week in comments - if you wish to share 🌺🌺

Have a great day 💕💕

Reality Isn’t Always What It Looks Like…

I visited the Optical Illusions Museum in Lyon and oh, it played with my mind! 😅 Every corner tricked me, every wall made me question what I was seeing. It’s wild how something can look so real and still be nothing but perception.

It honestly made me think… how often does life do the same? How often do we get deceived by appearances, by what we think is real?

Anyway, it was such a fun and eye-opening (literally 😂) experience, one of those moments that leaves you smiling and wondering. 🌻

Hello everyone! I am very happy to share that I have started my International Master in Advanced Methods in Particle Physics (IMAPP) as an Erasmus Mundus Joint Master’s (EMJM) European Union Scholarship Holder for 2025–2027.

You all were there with me, witnessing my love for physics and curiosity to understand things and my struggle to form a general and widely applicable understanding for the phenomenas. I never liked the fragmentation of concepts and theories in Physics. I believe there exists a unified theory that contains everything that universe ever had, is and will be. Let’s see how far I can go.

I am truly grateful for the privilege of being part of this inquiry through IMAPP and for the chance to learn under the guidance of some of the world’s leading researchers.

I’ll keep sharing my updates on LinkedIn and Instagram. Stay tuned.
Have a great day, everyone! 🚀

BTW. I uploaded an interesting short video that contains a glimpse of a day of my life. You can check it out.
